# Sisyphos vs Clusterduck

The clearest difference is rating: Clusterduck at 4.8 against Sisyphos's 4.1. Clusterduck also leads on ratings volume (174K vs 389) and update cadence (fortnightly vs every 2 months). Sisyphos's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.0). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sisyphos sells 5 one-off in-app purchases and Clusterduck sells 14 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Clusterduck holds the better App Store score, 4.8 against 4.1. That said, the two scores are not equally well evidenced: Clusterduck has 174K ratings behind it against 389, so its average is the more settled of the two. Written reviews point the same way: 82% of Sisyphos's written reviews are positive against 85% of Clusterduck's.

Sisyphos ships an update every 2 months, Clusterduck fortnightly. The most recent releases landed on October 22, 2026 and October 23, 2026 respectively.
